How Precision Tools Improve Multi-Layer Leather Punching

    Multi-layer material processing is widely used in footwear, leather goods, automotive interiors, and other manufacturing industries. Stacking multiple layers can improve production efficiency, but it also creates additional challenges for punching tools.

   When several layers of leather or composite materials are punched simultaneously, manufacturers may experience material clogging, tool breakage, inconsistent hole diameters, or rough edges.

Why Is Multi-Layer Leather Difficult to Punch?

Compared with single-layer leather, multi-layer materials require the punching tool to penetrate several layers with different thicknesses and structures. As the number of layers increases, cutting resistance can also increase.

If the tool material, hardness, geometry, or chip-removal design is not suitable for the application, several problems may occur：

• Material clogging
• Faster tool wear
• Tool breakage
• Inconsistent hole diameters
• Burrs and rough edges
• Reduced production efficiency

These issues can increase operating costs and affect the consistency of finished products.

Developing Tools for Multi-Layer Applications

Dongguan Zhongqi Precision Mold Parts Co., Ltd. has developed specialized punching tools for leather and composite material applications. The company has also conducted practical testing of punching solutions for stacked leather and composite materials using digital processing equipment. The objective is to provide more stable punching performance under demanding production conditions.

Customized Tools for Different Machines

Different CNC machines, materials, thicknesses, and processing parameters require different tool designs. Zhongqi supplies tools compatible with various digital cutting and punching equipment and supports customized shapes and specifications according to customer requirements.

For footwear, leather goods, automotive seat, and other manufacturers processing multi-layer materials, selecting the correct punching tool can improve production stability and reduce tool-related downtime.
